我有一个有效的网络服务和测试客户端,我可以拦截它们之间的消息。但是当我添加要发送到我的事件中心的代码时,客户端显示错误:
An unhandled exception of type 'System.ServiceModel.FaultException`1' occurred in mscorlib.dll
Additional information: The argument Endpoints is null or empty.
Parameter name: Endpoints
更详细的例外:
System.ServiceModel.FaultException`1[System.ServiceModel.ExceptionDetail]: The argument Endpoints is null or empty.
Parameter name: Endpoints (Fault Detail is equal to An ExceptionDetail, likely created by IncludeExceptionDetailInFaults=true, whose value is:
System.ArgumentException: The argument Endpoints is null or empty.
Parameter name: Endpoints

继承我添加的代码:
try
{
NamespaceManager namespaceManager = NamespaceManager.CreateFromConnectionString(GetServiceBusConnectionString());
Manage.CreateEventHub(hubName, 16, namespaceManager);
}
catch (Exception e)
{
Console.WriteLine("SetupEHError" + e);
}
EventHubClient client = EventHubClient.Create(hubName);
Console.WriteLine("eventhubclient iniciado");
EventData messageData = new EventData(Encoding.UTF8.GetBytes(serializedString));
try
{
client.Send(messageData);
Console.WriteLine("MessageData enviada");
}
catch (Exception e)
{
Console.WriteLine("ErrorMessage:" + e);
}
这是CreateEventHub方法:
public static void CreateEventHub(string eventHubName, int numberOfPartitions, NamespaceManager manager)
{
try
{
// Create the Event Hub
Console.WriteLine("Creating Event Hub...");
EventHubDescription ehd = new EventHubDescription(eventHubName);
ehd.PartitionCount = numberOfPartitions;
manager.CreateEventHubIfNotExistsAsync(ehd).Wait();
Console.WriteLine("Created");
}
catch (AggregateException agexp)
{
Console.WriteLine(agexp.Flatten());
}
}
WebService Console应用程序最多打印
Creating Event Hub
Created
所以我想我可能需要为WebService中的MessageInspector添加端点,以便能够将数据发送到服务总线事件中心。如果是的话,配置如何?
先谢谢

<强>背景强>:
ServiceBus SDK有两个主要接口:
aka Control Plane
),如创建删除主题/ EHubs等aka Data Plane
) - 从Topics / EventHubs发送/接收。这两个接口都需要自己的连接字符串才能连接到ServiceBus。例如:指定给NamespaceManager的连接字符串需要ManageClaims,而EntityClients只需要发送/接收索赔。
您使用EventHub Name创建了EventHubClient,并且没有在那里传递连接字符串。在这种情况下,从ServiceBus客户端sdk抛出上述错误 - 当连接字符串未通过app.config传递时。 要解决此问题,请更改此行(因为您直接为NamespaceManager使用ConnectionString而不使用任何app.config):
EventHubClient client = EventHubClient.Create(hubName);
将其更改为:
----edit-----
var eHubConnStr = GetServiceBusConnectionString();
eHubConnStr.EntityPath = eventHubName;
// Evaluate here, if you have to populate the Security related properties from the ConnectionString
// eHubConnStr.SasKey and SasKeyName to Send only or Recv only
----edit-----
EventHubClient client = EventHubClient.CreateFromConnectionString(eHubConnStr); // this connection string should be the EventHub Send conn str.
HTH! SREE

实际上我需要做的就是用连接字符串编辑我的Web服务服务器的app配置。似乎eventhubclient的Create方法接受了eventhub名称,然后转到appconfig获取密钥,因此它没有找到它。
